dc.descriptionIn this work, the char morphology from coal-sugarcane bagasse with concentrations of 0, 25, 50, 75 and 100 % w/w and particle sizes -0.25 mm and -20 mm was evaluated. The samples were fed to a devolatilization process at 900 °C in a tubular drop reactor (-0.25 mm) and a batch-type fixed bed reactor (-20 mm). The morphology of the char was determined through image analysis. The surface area was evaluated by BET analysis for particle size -0.25 mm. The results showed that for particle sizes -20 mm synergistic effects were obtained towards the generation of reactive morphologies (thin walls + thick walls) with the increase in bagasse concentration. It was found that coal generated a higher concentration of thick and solid wall morphologies.eng
dc.descriptionEn este trabajo se evaluó la morfología de carbonizados provenientes de mezclas de bagazo de caña de azúcar y carbón con concentraciones de bagazo de 0, 25, 50, 75 y 100 % p/p y tamaños de partícula -0.25 mm y -20 mm. Las muestras se alimentaron a un proceso de desvolatilización a 900 °C en un reactor tubular de arrastre (-0.25 mm) y un reactor de lecho fijo tipo batch (-20 mm). La morfología de los carbonizados se determinó a través de análisis de imagen. El área superficial se evaluó por medio de análisis BET para tamaño de partícula -0.25 mm. Los resultados mostraron que para tamaños de partícula -20 mm se obtuvieron efectos sinergísticos hacia la generación de morfologías reactivas (paredes delgadas + paredes gruesas) con el aumento de la concentración de bagazo. Se encontró que el carbón generó mayor concentración de morfologías tipo pared gruesa y sólido.spa
